Subject: [PATCH v2 24/34] media: iris: subscribe input and output properties to firmware

From: Vikash Garodia <quic_vgarodia@...cinc.com>

Driver can subscribe to different properties for which
it expects a response from firmware. Different SOCs
firmware can support different properties which can be
subscribed by driver.
HFI_CMD_SUBSCRIBE_MODE with HFI_MODE_PROPERTY - to subscribe
any property to firmware.

Also, set below mandatory properties on capture plane:
HFI_PROP_COLOR_FORMAT
HFI_PROP_LINEAR_STRIDE_SCANLINE
HFI_PROP_UBWC_STRIDE_SCANLINE.
